Tjs.

Do a search on Yss or emulator in the search term there are loads of answers. 👍

I measured the fork slider internal diameter and compared to YSS list,
238 is the diameter of the emulator

I did look into this last winter when rebuilding my LC.
I believe they do not fit as standard, but some modification is required, though exactly what, wasn't completely clear.
Due to this I didn't fit them to mine in the end.

You need to enlarge the hole(s) in the damper rod, 2 min job

You need to enlarge the hole(s) in the damper rod, 2 min job From memory as well as enlarging the existing holes, you need to drill some more. you need to make sure you deburr them too. Much more than 2 minutes, but a simple job. Jon |

100% the 238 is the correct kit for the 4LO, no machining to do they drop straight into the damper rods.👍

From memory it was a 2 minute job, that's including reading the instructions 😀

So moving on...
If one replaces the old springs with same dimension new ones,should these be reduced in lenght to compensate for the " height" of the emulator..
Tks..

Spring remains the same length, cut the top spacer down to suit, 20mm I seem to remember is the Emulator height.(I'm sure Jon will tell us)

Post by derek500 on Sept 23, 2023 19:06:22 GMT 1
Ah so no spacer means either cut down the springs, or can you modify top threaded caps?
OR wonder what it would be like with extra preload?

I fitted the YSS238 emulators to my 4L0 forks two years ago.
Drilled the damper rods as per instructions , cut 10mm of the tight wound end of spring and ground end flat. (Emulators add 15mm of preload).
ATF oil .
Emulators working well , done a few thousand miles , solo, two up and a weekend doing Curborough Twisty Sprint on it .
